MIRROR-HINGE.

SPECIFICATION forming part of Letters Patent No. 305,006, datedSeptember 9, 1884.

Application filed October 25, i883. (No model.)

To all whom it 11mg concern.-

Be it known that I, ANTON JELINEK, of

. Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Mirror-Hinges; and I do herebydeclare that the followingis afull, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of my invention is to provide a mirror-hinge which holds amirror at any desired angle to the normal vertical plane by means of thefriction created between the parts of said hinge by a coneavo-convexdiskspring.

In the drawings, Figure 1 is a perspective view of my improved hinge.Fig. 2 is vertical longitudinal section of the same.

Reference being had to the drawings, A and B represent cup-shaped lugs,both of which project at right angles from suitable screwplates 0, andboth of which when in position have their open sides face each other.The lug A has an annular flange, a, projecting from the inner edges ofthe mouth ofits open side, and the lug B has an annular rabbet, b,encircling the inner edge of the mouth of the open face of the same,which corresponds in dimensions to the flange a, resting therein,

,These two lugs are held together by a rivet,

D, having a head, (I, passing laterally and centrally through both lugsand through the concavo-convex disk-spring E, and then swaged. When theend 6 of the said rivet is swaged,

the diskspring E is securely held against the adjacent lug A, with theconcave side thereof facing inward, thus creating such friction betweenthe engaging surfaces of the springthat is, between the flange a andrabbet b, the disk'spring and lug A, the inner side of the head d of therivetand lug B, and between the inner surface of the swaged end 6 ofsaid rivet and the concavo-convex disk-springso that when applied to amirror. it will hold the same at any angle desired.

When applying my improved hinge, the necessity for drilling holes andthe labor of adjusting therein the ordinary pin is obviated. All that isrequired is the screwing of the screws through the screw-plates and intothe mirror-frames and uprights of the surrounding frame, respectively.

The principal feature of the invention claimed in these specificationsis the application of adisk-spring to a mirror-hinge; therefore What Iwish to obtain by Letters Patent is- A mirror-hinge consisting of twocup-shaped lugs, the edges of which overlap each other, screw-platesintegral with and set at right angles to said lugs, a rivet connectingsaid lugs, and a concavo-conveX spring at the end of said rivet, betweenthe head thereof and the surface of the contiguous lug.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presence of two witnesses.
